Performance of Pile Foundations with Internal Diaphragm in the Red Sea Formations
Salwa Yassin, MICE, CENG, Ph.D,
The heterogeneous nature and characteristics of coral formations and carbonate deposits in the Red Sea present engineers with a unique challenge when designing pile foundations. Recorded pile load test results indicate that pile capacity tends to be overestimated when adopting the common soil mechanics and foundation design methods. This is mainly due to the inherent uncertainty and high variability in the engineering properties of such formations and their particular characteristics behavior. Consequently, adopting the appropriate type of deep foundations with limiting values for skin friction and end bearing based on pile load test results are the choice for more realistic and economic design. This paper presents a comparison between driving records for two open-ended test piles driven offshore, with an internal diaphragm, and their correspondence theoretical driving resistances estimated by GRLWEAP program.
